Text = depends on strcoll(), which is locale-sensitive. It sure appears
that your locale is designed to ignore japanese characters :-(

We have heard before that RH9's default locale setting is seriously
broken. This seems to be additional evidence for that opinion. I'd
recommend re-initdb'ing in locale C.
Also, you say "your locale", but how certain are you that that is the
database's locale, and not just the one in your own user environment?
It'd be a good idea to use pg_controldata to check the database settings.
